In addition, as the oil gas and the air are easy to form an explosive mixture (the lower explosion limit is generally 1% -6%), the oil gas dissipation can cause the concentration of the oil gas around corresponding facilities to easily reach the explosion limit, and the oil gas gathered on the ground brings great potential safety hazards to enterprises and consumers, thereby endangering the safety production of the enterprises and directly influencing the health of operators and surrounding environment personnel. Therefore, it is necessary to recover the dissipated oil gas.

WO9604978 adopts active carbon as adsorbent, uses two-tower alternative regeneration-adsorption process, and uses vacuum pump to make pressure-swing desorption, and the desorbed gas is condensed and recovered by means of condenser. When the active carbon adsorbs oil gas components, the adsorption heat release enables the temperature of an active carbon bed layer to be greatly increased, and particularly when the oil gas concentration is high, the active carbon bed layer is easy to generate a local overheating phenomenon, so that the service life of the adsorbent is shortened, and potential safety hazards exist in the operation process. In addition, when the oil gas contains more high-boiling-point organic matters, the organic matters are easily adsorbed by activated carbon, but are difficult to desorb through vacuum pumping, which can remarkably reduce the service life of the adsorbent.

However, when the oil gas collecting space of the storage tank is at negative pressure (the working condition of negative pressure is mainly when large breath and small breath inhale), in order to ensure that the storage tank is not blocked due to the negative pressure, the breather valve needs to inhale air to the oil gas collecting space, so that the collected oil gas contains air (oxygen) components, and the safety risk of the external floating roof tank is increased; in addition, the storage tank still has the problem of exhausting waste gas by breathing in size.
